Attached is an attempt to implement this idea.  One could use
bb.fetch.describe_revision for, say, AUTOPV generation, like
bb.fetch.get_srcrev is used for AUTOREV.

Example (from bitbake.conf):

  AUTOREV = "${@bb.fetch.get_srcrev(d)}"
  AUTOPV = "${@bb.fetch.describe_revision(d)}"

It would be nice if somebody could review the attached patch, since I
don't know much about bitbake internals.

P.S.: sorry if this message is messing up threading in your email client.
I'm replying to a fake original message, since I don't have the original
one.

Best wishes.
Mario
